Abstract (en)
[origin: WO8903338A1] A turret device (12) which is anchored to the ocean floor, and a floating structure (1) which is supporting the turret device and can swing freely around it. The turret comprises a lower radial sliding bearing (4, 5), with relatively small width and large diameter and an upper spherical axial bearing (2, 3) with relatively small diameter. The rest of the turret can be disconnected from the upper spherical bearing (2, 3) by a multiple thread, non-selflocking screw connection between a sleeve (35) and a hub (37), which in connected position are locked by a dog clutch (36). When disconnected, the turret will sink to a stable equilibrium a distance below the ocean surface. The turret device can be fitted forward of the bow of a ship (1), or between the bow and midship.
